The worst excuse I’ve ever heard for gendering books is that, “What if it confuses my kid? What if they grow up gay or trans because I let them read about too many girl/boy things?”
Your son’s first crush might be the rowdiest boy in a story about boys doing “boy things”. Your daughter might want to be with the gentle seamstress who makes the magic cloak, not be her. Your tomboy might be a boy, and he might identify with the protagonist’s science-loving crush, not her.
Your kid is your kid, and they will be who they are meant to be. Give them all the boy/girl books you want, but you can’t control how they’ll feel about them, or what they’ll take away from the story.
As a parent, you can’t iron the world flat to keep your kid from stumbling, but you can absolutely prepare them for the bumps. If they walk an unexpected path, having read more widely will only ease their way, and get them where they need to be.
